Hello friends of the forum are developing a Dll in VFP6.0Sp5 but not you that
to make that when the Dll throws an error this he/she informs the user the error
that happened as this way:

Ejplo Dll
DEFINE CLASS Prueba AS Custom OLEPUBLIC
Procedure Suma
parameters valor1,valor2,valor3
On Error xerror=.t.
suma=valor1+valor2+valor3
If xerror <--- Si Ocurrio el Error enviar un mensaje al Usuario
return "Error en el Traspaso de alguna variable" <- Un Ejmplo
cualquiera
Else
return suma
Endif
Enddefine


In my Button of my form that he/she calls to the Dll
oPrueba=Createobject (" Prueba.prueba ")
Xsuma=oPrueba.suma(1,1,A) <--- I send him variable TO as character so that me
throw the Error

I arrive until here one doesn't eat to show the Error that my Dll sends sum since
it can return numeric as the message of Error it can return, when
I activate the On Error in my Form I hurtle Error in Ole Custom....... but not
it throws me the personalized message that I want somebody he/she can tell me as giving solution to
This.

He/she notices:
As it could manage the transactions in an environment multiuser by means of Ado

Thank you for the whole help that you/they can offer me
